Olivia Munn could probably kick Aaron Rodgers' butt (VIDEO)

Saturday, January 31: Green Bay Packers quarterback Aaron Rodgers and girlfriend actress Olivia Munn pose on the red carpet prior to the NFL Honors award ceremony at Symphony Hall in Phoenix, where Rodgers was selected the AP Most Valuable Player.

Green Bay Packers quarterback Aaron Rodgers has a beautiful girlfriend in actress Olivia Munn, but don't let her looks fool you -- she's more of a Ronda Rousey than a Marilyn Monroe.

Don't believe us? Just check out the Instagram video of Munn and Rodgers below.

While Munn practices a nasty combination of kicks, each with enough force to knock someone out cold, Rodgers can be seen throwing some stationary jabs in the background. Although Rodgers looks like he can hold his own in a fight, it would be in his best interest not to pick one with Munn -- she's practically a ninja.
